Electronictization-A Foundation for grid modernization

Chinese Journal of Electrical Engineering 2015年第1期1卷 1-8页

作者： Don Tan IEEE Power Electronics Society New JerseyUSA

Smart grid is the flag under which the US DoE has been mobilizing efforts to modernize the *** is the first step towards a smart modern *** is a process that transforms the grid from electrical and electromechanical(EE)to electronic,electrical and electromechanical(EEE),laying down the very basic foundation for the modern *** things grid connected(ATGC)has five groups of essential hardware:1)grid interface(smart)inverters;2)Hardware for flexible AC transmissions;3)Intelligent electronic power transformers(grid scale);4)Solid-state circuit breaker,current limiters,smart fuses and sensors;and 5)Multi-port bidirectional power&control *** and deployment of ATGC will be a grassroots drive to transform the grid from an old passive technology to a new active technology based on electronic power transmission,distribution,processing and *** modernization represents a win-win-win situation for the environment(Government),consumers,and grid owners/operators.

Structured Microgrids (SμGs) and Flexible Electronic Large Power Transformers (FeLPTs)

引用

CES Transactions on Electrical Machines and Systems 2020年第4期4卷 255-263页

作者： Don Tan Northrop Grumman Space Systems

Structured microgrids(SμGs)and Flexible electronic large power transformers(FeLPTs)are emerging as two essential technologies for renewable energy integration,flexible power transmission,and active control.SμGs provide the integration of renewable energy and storage to balance the energy demand and supply as needed for a given system ***’s flexibility for processing,control,and re-configurability offers the capability for flexible transmission for effective flow control and enable SμGs connectivity while still keeping multiscale system level *** adaptors for combined heat and power have demonstrated significant economic benefits while reducing environmental foot *** bring tremendous benefits to utility companies *** storage and active control capabilities,a 300-percent increase in bulk transmission and distribution lines are possible without having to increase capacity.SμGs and FeLPTs will also enable the utility industry to be better prepared for the emerging large increase in base load demand from electric transportation and data *** is a win-win-win situation for the consumer,the utilities(grid operators),and the environment.SμGs and FeLPTs provide value in power substation,energy surety,reliability,resiliency,and *** is also shown that the initial cost associated with SμG and FeLPTs deployment can be easily offset with reduced operating cost,which in turn reduces the total life-cycle cost by 33%to 67%.

Towards a (More) Electronic Transmission and Distribution (eT&D)

引用

CES Transactions on Electrical Machines and Systems 2017年第1期1卷 15-25页

作者： Don Tan Damir Novosel IEEE NGAS Quanta ABB KEMA T&D US

The challenges and the path towards a(more)electronic transmission and distribution(eT&D)is presented in this *** challenges are first identified together with key stakeholders in the drive for grid modernization.A fundamental question is then asked about the investment *** basic characteristics are reviewed,leading to the composition of structured microgrids as the basic functional cell of a modern *** example of fractal radial structure and one fractal meshed structure are *** likely evolution path is then proposed together with basic technology *** foundation technologies are discussed in detail,including adiabatic power conversion,3MC technology,medium voltage conversion,distribution-level electronic power transformer and FACTs hardware integration,and back-to-back converters as a universal interconnect *** rapidly emerging on-wire sensing technology is also *** is pointed out that the distribution-level large electronic power transformer will provide a key component to enable hybrid ac/dc grid flow control and ancillary support for a flexible electronic transmission and distribution(eT&D)systems.
